Application March 14,

3 Claims.

The present invention relates to new and useful improvements in stovepipe anchors and has for its primary object to provide, in a manner as hereinafter set forth, a device of this char- 5 acter embodying novel means through the medium of which movement of the pipe in either direction will be positively prevented.

Another very important object of the-invention is to provide a stovepipe anchor of the aforementioned character comprising unique means for looking the device in operative position.

Other objects of the invention are to provide a stovepipe anchor of the character described which will be comparatively simple in construction, strong, durable, highly efiicient and reliable in use, compact and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a view in side elevation of a stovepipe equipped with an anchor constructed in accordance with the present invention.

Figure 2 is a cross sectional view, taken substantially on the line 2-2 of Fig. 1.

Figure 3 is a vertical longitudinal sectional view, showing the anchor in released position.

Figure 4 is a view substantially similar to Fig. 3 but showing the anchor in looking position.

Figure 5 is a detail view in perspective of the hook operating shaft.

Figure 6 is a detail view in perspective of the hook.

Referring now to the drawings in detail, it will be seen that the reference numeral l designates a portion of a chimney having formed in one of the walls thereof the usual opening 2 for the reception of a stovepipe section 3. It may be well to here state that the use of the invention with furnaces as well as stoves is contemplated. Mounted on the pipe 3 is a conventional collar 4 which abuts the chimney l around the opening 2.

The embodiment of the present invention which has been illustrated comprises a shaft 5 50 of suitable metal which is journalled in vertically aligned openings 6 which are provided therefor in the pipe 3. At its upper end, the vertical shaft 5 terminates in an operating handle 1. Threaded on the lower end portion of the shaft 5 beneath the stovepipe 3 is a wing nut Cal Evans- 1939, Serial No. 261,847

8. The shaft 5 has formed in its lower portion a substantially U-shaped crank 9 thepurpose of which will be presently set forth.

The reference numeral ll! designates a flat bar of suitable metal having formed in one end portion thereof an elongated opening H (see Fig. 6) for the reception of the crank 9 for operatively connecting said bar to the shaft 5. Formed integrally with the other end of the bar l isa depending hook l2 which terminates, at its lower end, in inturned teeth or prongs l3 which are adapted to bite into the chimney l.

It is thought that the manner in which the invention functions will be readily apparent from a consideration of the foregoing. Briefly, with the parts in the position shown to advantage in Fig. 3 of the drawings, the stovepipe 3 is inserted in the opening 2 of the chimney I. This permits the hook l2 to drop down in the chimney l below the opening 2. The shaft is then rotated approximately one-half of a revolution through the medium of the handle 1, thus pulling the bar it outwardly through the medium of the crank 9 for embedding the teeth or prongs it of the hook I2 firmly in the chimney I. As the shaft 5 is thus rotated the bar It! slips downwardly off the crank 9 to the positionshown in Fig. 4. of the drawings. Thus, thehook 12 secures the stovepipe 3 against pulling out of the chimney andthe free end of the handle 1 is engaged with the collar 4 in a manner to positively prevent said stovepipe from being pushed farther into the chimney. Then, by tightening the wing nut- 8 the shaft 5 is locked in this position. To release the stovepipe whendesired, the wing nut 8 is removed and the shaft 5 is pulled upwardly out of the bar it. The stovepipe 3 may then be slipped out of the opening 2! leaving the bar it! with the hook l2 thereon in said opening from which they may conveniently be removed by hand.

It is believed that the many advantages of a stovepipe anchor constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

1. In combination with a chimney having an opening therein and a stovepipe engaged in the opening, a shaft journaled in the stovepipe, a crank portion in said shaft, a bar in the stovepipe having one end portion loosely connected to the crank portion for actuation by the shaft, a hook on the other end of the bar engageable in the chimney for securing the stovepipe against outward movement relative to the chimney, and an operating handle for the shaft on one end thereof, said handle being engageable with the chimney for securing the stovepipe against movement in the opposite direction.

2. In combination with a chimney having an opening therein and a stovepipe engaged in the opening, a rotary shaft extending through the Stovepipe, said shaft including a crank adjacent the periphery of the Stovepipe, a bar operable in the stovepipe and having one end portion loosely connected to the crank, a hook on the other end of the bar engageable in the chimney for preventing withdrawal of the Stovepipe, a nut threaded on one end portion of the shaft and engaged with the Stovepipe for clamping the bar between the crank and said Stovepipe, and means for rotating the shaft, said means including a handle on the other end of the shaft, said handle being engageable with the chimney and also constituting means for retaining the stovepipe against inward movement in the chimney.

3. In combination with a chimney having an opening therein and a stovepipe engaged in the opening, a vertical rotary shaft extending through the stovepipe, a crank on .the lower portion of the shaft operable in the Stovepipe, said crank extending in one direction from the shaft, a bar operable in the stovepipe and having one end portion loosely connected to the crank, a hook depending from the other end of the bar and engageable in the chimney, inturned prongs on the lower end of said hook adapted to bite into the chimney, a nut threaded on the lower end portion of the shaft and engaged with the Stovepipe for clamping the bar between the crank and said Stovepipe, and a handle on the other end of the shaft projecting in the opposite direction therefrom relative to the crank, said handle constituting means for rotating the shaft, said handle being engageable with the chimney and further constituting means for retaining the stovepipe against inward movement in the opening.
